The tornado, which hit Oklahoma City and surrounding areas earlier this week, left 24 dead and more than 370 people injured.

"The impact of the tornados in Oklahoma and the Midwest was devastating and the road to recovery will be long for many families," said the American Red Cross's chief development officer Neal Litvack.

"Through the generosity of Carrie, the American Red Cross can quickly respond with shelter, food and comfort now, and with lasting help as they move toward recovery,” he continued.

The six-time Grammy winner also recently donated to the organization's relief fund after Storm Sandy devastated New Jersey last year.

Underwood performed her last performance of the "Blown Away Tour" on Thursday.

Also just announced, fellow Oklahoma native and "The Voice" coach Blake Shelton will be holding a benefit concert for disaster relief next Wednesday, which will air live at 9 p.m. ET/PT on NBC, as well as NBCU sister networks Style, G4, Bravo, E! and CMT on either a live or delayed basis.
